There are AB3 type and sucrose solutions with 0.1M concentration each....
Solution:
Given, osmotic pressure of AB3 solution = 0.72 atm
osmotic pressure of sucrose solution = 0.24 atm
Concentration of AB3 solution = 0.1 M
Concentration of sucrose solution = 0.1 M
Let us calculate the van't Hoff factor (i) for both the solutions using the formula:
i = (observed osmotic pressure)/(expected osmotic pressure)
where, expected osmotic pressure = (RT/V) x number of particles
For sucrose solution:
expected osmotic pressure = (RT/V) x 1 (as sucrose does not dissociate in solution)
∴ i = (0.24)/(0.0831 x 298 x 1/1000)
i = 0.996
For AB3 solution:
expected osmotic pressure = (RT/V) x 4 (as AB3 dissociates into 4 particles)
∴ i = (0.72)/(0.0831 x 298 x 4/1000)
i = 2.10
Now, we know that i = (1 + α(n-1))
where, α = degree of dissociation
n = number of particles after dissociation
For AB3, n = 4 (as it dissociates into 4 particles)
∴ 2.10 = (1 + α(4-1))
α = 0.67
Hence, the fraction of AB3 dissociated is 0.67. Therefore, the correct answer is option 3) 0.67.
